What Is 11taxassist?
What Is 11taxassist?
11taxassist (11taxassist.co.uk) is a UK-registered HMRC-recognised MTD filing tool operated by 11taxassist Limited (Company Number: 16416027), based in Reading, England. The platform focuses exclusively on the submission step of Making Tax Digital — enabling sole traders, landlords, freelancers, and tax agents to submit MTD quarterly updates and the Final Declaration directly to HMRC with automatic tax calculations, error validation before submission, and instant HMRC confirmation with reference numbers.
11taxassist's core proposition is radical simplicity and affordability: instead of a monthly or annual subscription, users pay just £5.99 per filing (currently 63% off from the regular price of £15.99). There are no subscriptions, no contracts, and no ongoing commitments. For MTD ITSA, the £5.99 fee covers all 4 quarterly submissions plus the Final Declaration (5 submissions total per year). For MTD VAT, the same £5.99 fee covers 4 quarterly VAT submissions per year. The platform supports both individual filing and agent filing (accountants and tax agents with an Agent Services Account can file on behalf of clients).

Making Tax Digital Compliance
How 11taxassist Handles MTD for Landlords and Sole Traders
11taxassist is HMRC-recognised for MTD ITSA and supports quarterly updates plus the Final Declaration for self-employment, UK property, and foreign property income. The platform provides automatic income and expense calculations, displays allowable and disallowed expenses side by side, calculates taxable profit instantly from submitted figures, and generates an HMRC confirmation receipt with a reference number after each submission. 11taxassist also supports MTD for VAT with spreadsheet (Excel) upload. Agent filing is fully supported — tax agents with an Agent Services Account can manage clients' MTD ITSA and VAT submissions through the platform. However, 11taxassist does not maintain digital records throughout the year — users must keep their own records and enter figures into the platform at each quarterly filing point.

11taxassist: No Property-Specific Features
11taxassist does not offer any property-specific features.

The platform is a filing tool — landlords enter their income and expense totals at each quarterly filing point. 11taxassist does provide downloadable record templates (Income Summary Template and Expenses Tracker Template) that follow HMRC's ITSA algorithms, but these are offline templates, not integrated software features.

Bookkeeping, Accounting & Digital Record Keeping
11taxassist: No Bookkeeping — Filing Only with Auto-Calculations
11taxassist does not provide bookkeeping, accounting, or ongoing digital record keeping. The platform's role begins at the filing step: landlords enter their income and expense figures, the software auto-calculates taxable profit (showing allowable and disallowed expenses side by side), validates for errors, and submits to HMRC. There are no bank feeds, no chart of accounts, no journal entries, and no financial reports. Records must be maintained elsewhere by the landlord.

Invoicing, Expense Tracking
11taxassist: No Invoicing or Expense Tracking
